It is considered that juice is useful to health – it the statement is right only for natural fresh juices and that with some restrictions. Store juice in the majority not only doesn't bring benefit, but also can do harm. If you didn't buy the juice extractor yet, then it is necessary to learn to choose quality juice in shops.
Harm of store juice
Producers of juice claim that their products of 100% natural, without use of preservatives or fragrances. Nevertheless they are made not of fresh fruit, and from a concentrate – such juice is called restored, always writes about it on packings, but not all know, what does it mean. In this concentrate much less vitamins, than in fresh fruit, it is diluted with water to receive juice.
At the majority of store juice the period of storage makes from several months to one year whereas any fresh juice vanishes for several days. In natural fruit the process of fermentation with release of gases which inevitably would blow up packing begins over time. That not to allow it, producers add preservatives to juice or subject them to heating – temperature influence prolongs a period of storage, but destroys almost all remained vitamins. As a result the advantage of juice decreases almost to a minimum.
The majority of the juice presented on store counters actually are nectars, but not all producers directly write about it in a visible place packings. Nectar is a sugar syrup with addition of a small amount of a fruit concentrate. The amount of sugar in such drinks is huge and works great mischief to a human body. The fact is that drinks usually aren't perceived by the person as an essential product in the power plan though actually one pure-pak of nectar can contain 500 and more kilocalories (that to approximately equally full-fledged soup and second course lunch) and instead of losing weight thanks to such "correct" food, the person begins to gain weight.
Cold juice seems less sweet, and the person drinks more, problems with a metabolism and excess weight as a result appear.
Also fragrances and dyes which aren't useful to health too are added to nectars for giving to syrup of taste and color. That small percent of a fruit concentrate which is used for nectar preparation is usually made of the low-quality, unripe fruit which don't have a brisk taste and giving to drink acid.
Advantage of store juice
If to buy juice without addition of sugar, then he nevertheless is capable to bring small benefit – after all in it there is a small amount of vitamins. At the same time it is important to show consideration for the choice of drink. In structure there shouldn't be a sugar and also sweeteners – sucrose, aspartame, fructose, and the share of a concentrate has to make not less than 70%.
As a rule, quality juice differs in higher price as they are made of good ripe fruit which cost expensive.
It is even more useful to drink fresh juices – the packaged fresh juices which are stored several days. They usually are on sale in large supermarkets, but at their production preservatives and other additives can be applied too.
